Magnetic separation nickel nanoparticles

Apr 29, 2020

Aug 01, 2021 This method uses the affinity of poly-histidine peptides to metal ions, such as nickel, copper, cobalt, iron, gallium or zinc to specifically bind the proteins. Magnetic nanoparticles, decorated with these specific metal ions have proven to be very powerful sample separation and purification tools for histidine-tagged proteins . As we know, the purification of recombinant proteins is one of the most
